The Trans-Sierra Xtreme (TSX) Challenge and Grand Canyon Challenge are a series of inspirational guided backpacking treks across Kings Canyon and Sequoia National Park, and Grand Canyon National Park. They are among the most challenging and rewarding experiences that California and Arizona have to offer. You’ll traverse awe-inspiring terrain, completely unplugged, with a small group and incredibly experienced guides. While the treks can be intense, no prior backpacking experience is required and all ages are welcome. Just bring your mental toughness, positive attitude and be ready for the challenge of a lifetime.
